FAN ATTACHMENT FOR ROCKINGr-CI-IAIRS.

Application led November 10, 1913.

Specification of Letters Patent.

Patented Sept. 15, 1914.

Serial No. 800,020.

To all whom t may @0n-cern Be it known that I, I/VILLIAM W. SHIRLEY, acitizen of the United States, residing at Bualo, in the county of Erieand State of New York, have invented new and useful Improvements in FanAttachments for.

Rocking-Chairs, of which the following is a specification.

This invention relates to fan attachments for rocking chairs and cradlesin which the fan is automatically vibrated by the rocking motion of thechair or cradle.

The object of my invention is the production of a neat and simpleattachment of this character which can be manufactured at small cost andwhich is not liable to get out of order.

In the accompanying drawings: Figure 1 is a side elevation of a rockingchair equipped with the improved attachment. Fig. 2 is a rear elevationof the lower portion of the chair and the mechanism attached thereto.Fig. 3 is a perspective view of the weighted lever and adjacent parts.Fig. t is a top plan view of the upper portion of the attachment. Fig. 5is a horizontal section on line 5 5, Fig. 1, showing the upper fasteningmeans of the device.

Similar characters of reference indicate corresponding parts throughoutthe several views.

1 indicates a substantially upright rock shaft preferably arrangedcentrally at the back of the chair and extending above and below theback. This shaft is journaled near its lower end in a bracket 2 rigidlysecured preferably to the underside of the chair-seat andI near itsupper end in a tube or bearing 3 arranged in a bracket or collar 4carried by the chair-back. The bracket 4C shown in the drawings has aplate 5 shaped to conform to the curved upper cross-bar 51 of thechair-back and detachably secured thereto by suitable clamps 6. The tube3 is preferably movably clamped in the collar 4: which latter has athumb or set screw 7 for this purpose.

At its lower end the shaft 1 carries a rock arm 8 connected by a link 9with a weighted lever 10 preferably arranged underneath the chair-seatand mounted on a transverse pin 11 carried by the front end of thebracket 2. In the construction shown, the front end of this link isconnected with the upper arm of the weighted lever by a universal jointconsisting of a transverse pin 12 capable of oscillating in an openingin said lever and having a vertical opening through which the angular ordownwardly-bent front end of the link passes, as best shown in Fig. 3.The lever 10 carries a comparatively heavy weight 13 which may beadjustably attached thereto by bolts 14 passing through one or more setsof a vertical row of registering holes formed in said lever and theshank 15 of the weight.

To the projecting upper end of the rock shaft 1 ris secured a gear wheelor segment 16 by a set screw 22 or other fastening. This segment mesheswith a pinion 17 secured to a substantially horizontal rock shaft 18arranged on the front side of the shaft 1 and overhanging the chairseat. This pinionshaft is supported in a frame 19 secured to the upperend of the bearing tube 3 by a set screw 20, or other suitable means.The shaft 18 carries at its front end a suitable fan 21 preferablyarranged in a pendant -position over the users head.

In rocking the chair, the weight 13 tends to hold the lever 10 in asubstantially vertical position, and this lever in turn holds the link 9against longitudinal movement. The upright rock shaft 1 moves back andforth with the chair-back and seat and the rock-arm 8 tends to followthese movements of said shaft, but as the link 9 is practically heldstationary, said rock arm 8 is swung forward on the rearward stroke ofthe chair and swung backward on the forward stroke of the chair, therebyrocking the shaft 1 which in turn actuates the shaft 18 and the fan 21attached thereto.

As the weighted lever is located underneath the chair seat, it is out ofthe way and does not render the chair unsightly. None of the parts ofthe attachment are mounted on the arm rests of the chair and the devicetherefore in no way interferes with the comfort or convenience of theoccupant of the chair.

Should it be desired to move the fan out of the way, this can be easilydone by loosening the set screw 7 and reversing or swinging the frame 19and the fan shaft, together with the tube or bearing 3, around to therear side of the chair-back.

The attachment can be readily applied to Copies of this patent may beobtained for ve cents each, by addressing the Commissioner of Patents,

Washington, D. C.

the seat and the back of any ordinary roCk- Ving chair, as shown, or tothe bottomand the side of acradle.

I claim as my invention:

In an automatic fan attachment for rocking chairs, the combination of abracket adapted to be secured beneath thel chairseat, a Weighted leverpivoted to said bracket, a substantially upright rook shaft supported onthe back of the chair and provided With a rock arm, a connectionextending vfrom said rock arm to said Weighted lever, a Vgear segmentsecured to the upper portion of sadfrook shaft, and substantiallyhorizontal fan-shaft extending forwardly from the upper portion of saidupright'shaft, the fan-shaft having a pinion which engages said segment.Y
